IMPROVEMENT IN STEAM-GENERATORS.

Specification forming part of Letters Patent No. 215,834, dated May 27;1879; application liled March 10, 1879.

To all whom it may concern:

Be it knownuthat I MICHAEL J. ORIELLEY, Vof the city of Buffalo, in thecounty of Erie and useful Improvements in Steam-Generators, of which thefollowing is a specilication, reference being had to the accompanyingdrawings.

This invention relates to a steam-generator designed more particularlyfor heating` purposes, and has for its object the construction of asimple, cheap, efcient, and safe generator, which may be readily takenapart when required.

My invention consists of a steam-generator composed of horizontal andvertical pipes, arranged to form horizontal dues between the pipes, aswill be hereinafter fully set forth.

In the accompanying drawings, Figure l is a side elevation of myimproved generator with one of the side walls removed. Fig. 2 is a frontelevation of the generator. Fig. 3 is a partly sectional plan View. Fig.4is acrosssection in line x x, Fig. l. Fig. 5 is a view showing amodified mode of constructing the horizontal pipes.

Like letters of reference designate like parts in the several gures.

A represents the grate; B, the fire-door; O, the ash-pit; D, the ash-pitdoor; E, the inclosing brick-work; F, the front plate, and G Gr thedoors thereof.

H H1 H2 are three horizontal sectionspr groups of pipes constituting myimproved generator. Each section is composed of a series of horizontalpipes, z', arranged closely together and transversely to the directionof the draft, so as to form horizontal partitions, which separate oneiue from the other. k are verti- -cal pipes, arranged near each end ofthe horizontal pipes i, for connecting the latter with a horizontalmanifold or main pipe, L, run- The vertical pipes k are provided attheir ends with right and left hand screw-threads, and tap directly intothreaded openings in the pipes and manifolds L. m are fittings arrangedat the ends of the manifolds L, and n n' are short pipes provided withright and left hand screwthreads for connecting the fittings m.

In the drawings, the pipes a at the front of the generator are arrangedvertically, andthe pipes Vn at the rear horizontally; but eitherarrangement may be used at both ends, as may be preferred.

O is a steam-drum, connected with the upper section, H2, by pipes p, andp is the pipe by which the steam is conducted to the radiators. q is thevertical water-supply pipe connecting the sections H Hl H2 at the rear.

The horizontal pi pesi are closed at the ends by any suitable means. Asshown in Figs. l, 3, and 4, their ends are closed by screw-plugs itapping into the pipes, while in Fig. 5 their ends are shown closed byscrew-caps r, inclosing the end of each pipe.

The last-mentioned construction renders it necessary to bend one end ofeach pipe, as clearly shown in the figure, to make room for thescrew-caps.

The horizontal-pipes i of the lowest or rst section, H, are arranged tolie closely against the front of the generator, and to leave a spacebetween the last pipe z' of the series and the rear wall of thegenerator for the passage of the flame into the next Hue above.

The pipes i of the second section, H1, lie closely against the rear walland leave a passage at the front, and the sections alternate in thismanner to the top of the generator, where the hot air and gases escapeinto the smokepipe or chimney s. T are open frames set in the side wallsof the generator opposite the ends of the horizontal pipes t',and'provided with hinged doors t, so that upon opening the doors andremoving the plugs or caps closing the ends of the pipes i the lattercan be readily cleaned out.

The water enters the lower section, H, through the pipe q, and its levelis preferably held midway between the top and bottom of the generator."YThe Vwater is divided in my improved generator into very small bodies,which are heated very quickly and present a large surface to the fire,thereby enabling the generator to make steam rapidly with a veryeconomical 'consumption of fuel. The small diameter of the pipes ofwhich the generator is composed renders the apparatus capable ofsustaining a great pressure safely, and effectually guards againstexplosions.

Upon disconnecting the short pipes n at the front, and the pipes n andfittings m at the rear, any one of the sections H 'H' H2 can beWithdrawn through the front doors G when required to be repaired.

"When the rear connectingpipe n and littings m are arranged on the innerside of the rear Wall, it is not necessary to disconnect the fittings mat the rear in order to withdraw a section.

I claim as my inventionl. A steam-generator composed of two or moresections, HH' H2, each composed of horizontal pipes t', arranged closelytogether and transversely to the direction of the draft, vertical pipes7c, and manifolds L, arranged parallel with the draft, the differentsections forming horizontal fines, one above the other,

through which the draft passes successively, substantially as set forth.

2. A steam-generator composed of two or more horizontal sections, H HH2, each composed of horizontal pipes i, vertical pipesk, and manifoldsL, and right and left hand threaded pipes m, connecting the differentsections, so that each section can bc readily rcmoved, substantially asset forth.
